Hey bowling,
Depending on your desired reaction, the GP2 is an easy 8-10 boards stronger compared to your Depth Charge. Like Clint mentions, it will handle the heavier oil without a problem. If you can give us a little more personal info (like your pap), we'd be glad to try and help suggest a layout for you, thanks.
